Full title and description

Standard Test Method for Determination of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatography and Chemiluminescence — ASTM D5504-20. This standard specifies a GC (gas chromatography) procedure with chemiluminescence detection for speciated volatile sulfur compounds in high-methane gaseous fuels (for example natural gas) and similar gaseous samples; it reports both individual sulfur species and total sulfur determined as the sum of quantified components.

Abstract

ASTM D5504-20 describes a laboratory analytical method using gas chromatography coupled with a chemiluminescence sulfur detector to identify and quantify volatile sulfur-containing compounds (such as hydrogen sulfide, carbonyl sulfide, mercaptans and other low‑molecular-weight sulfur species) in natural gas and other gaseous fuels. The method provides low-level detection (reported in picograms of sulfur per sample) across a wide dynamic range and reports results as speciated concentrations and total sulfur.

Scope

The test method is primarily intended for determination of speciated volatile sulfur compounds in high‑methane gaseous fuels (natural gas) but has also been applied to other gaseous matrices (air, landfill/digester/refinery fuel gases). The method’s detection capability is reported in terms of picograms of sulfur per sample with a working detection range that can be extended by dilution or changing the sample loop; it does not claim to identify every possible sulfur species, only those that elute under the selected chromatographic conditions. Users must establish appropriate safety and regulatory practices before use.

Key topics and requirements

• Analytical technique: gas chromatography with chemiluminescence sulfur detection.
• Analytes: speciated volatile sulfur compounds (examples include hydrogen sulfide, carbonyl sulfide, methyl mercaptan and other low‑molecular‑weight sulfur species).
• Performance: low-level detection (reported in picograms of sulfur), broad dynamic range (typical reporting range 0.01 to 1000 in the method’s units for a 1 µL/1 cc sample loop equivalent); method precision statements established by interlaboratory study.
• Calibration and quantitation: requires appropriate calibration standards for individual sulfur species and procedures to sum speciated concentrations to total sulfur.
• Limitations: only compounds that elute under chosen chromatographic conditions are quantified; dilution to extend range will reduce precision.

Typical use and users

Laboratories performing quality control and compliance testing on natural gas and gaseous fuels, refineries and gas-processing facilities monitoring sulfur species, environmental laboratories analyzing trace sulfur in gas samples, and equipment manufacturers or research groups validating catalyst or process susceptibility to sulfur contamination. The method is used where low‑level, speciated sulfur information is required for process control, safety, odor/corrosion assessment, or regulatory reporting.
